Southern Seoul

This is a look at the new Sillim LRT tunnel, now active. I waited for the train but it took a while and I needed to go to the bathroom.

So I went here instead.

More information, although RAS Korea President Steve Shields knew a lot more.

The way down.

It was nice and cool down here.

Here's a different-shaped tunnel section. You can see how the styles change per segment.

They call this shape horseshoe.

This section is called...

Rectangle. In English, it would be concrete box, possibly reinforced concrete box.

This is also horseshoe, but with stonework. Gonna guess it's the oldest style.

And another concrete box.

Time to turn around and head back.

Some interesting contrasts.

We couldn't go that way.

The entryway.
